A test device for a cell sorting machine

Abstract

The invention discloses a testing device for a battery core sorting machine. The testing device for the battery core sorting machine comprises a machine frame (1), and is characterized in that a lifting cylinder (2) which is driven by a pneumatic control system is fixed to the machine seat (1); a fixed block (3) which is controlled to ascend or descend by the lifting cylinder (2) is fixed to an output shaft of the lifting cylinder (2); a conveying platform (4) which communicates with a discharging channel of an external feeding device and is used for receiving a battery core for testing is arranged above the fixed block (3); a conveying belt (5) is arranged on the surface of the conveying platform (4); and the side walls of the fixed block (3) are also connected with a testing mechanism (6) with a plurality of testing units (9) with different sizes. The testing device for the battery core sorting machine is simple in structure and convenient to operate, and can be suitable for the useof the battery cores with various sizes and specifications.

Description

technical field [0001] The invention relates to the technical field of testing devices, in particular to a testing device for a cell sorting machine. Background technique [0002] Lithium batteries have certain differences. When used in combination, the consistency of lithium batteries is required to be very high. Therefore, it is necessary to use a cell sorting machine to test the capacity, voltage, and internal resistance of each battery before the battery is assembled. And classify and filter before grouping. In the prior art, the test device in the cell sorting machine can only test cells of one size. Since the cell sizes are different, the contact area between a single test probe and the cell is also different. When the contact area between the test probe and the battery cell is small, it will affect the accuracy of the test result; and once the size of the battery cell to be tested does not match the test device of the battery cell sorter, the manufacturer needs to us...

Problems solved by technology

In the prior art, the test device in the cell sorting machine can only test cells of one size. Since the cell sizes are different, the contact area between a single test probe and the cell is also different. When the contact area between the test probe and the battery cell is small, it will affect the accuracy of the test result; and once the size of the battery cell to be tested does not match the test device of the battery cell sorter, the manufacturer needs to use its own company's The size of the battery is individually customized, which will have the following disadvantages: first, the cost of input will be increased by separately customizing the equipment that matches the battery size; second, when the customized equipment fails, the after-sales maintenance time is longer The equipment is idle due to the lack of the same parts, which directly affects the detection speed of the battery cells, which greatly reduces the work efficiency; in addition, the existing test devices of the battery cell sorting machine often have complex structures and cumbersome operations. defect
